DRAFT-YOKE FOR RAILW'AY-CAR DRAFT-RIGGINGJ Specification of LettersPatent.

Patented Sept. 19, 1916.

Be it known that I, JOHN F. OCONBOR, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Draft-Yokes forRailway-Car Draft-Rigging, of which the follmving is a full, clear,concise, and exact description, reference being had to theaccompanyingdrawings, forming a part of this specification.

My invention relates to improvements in draft gear yokes for railway cardraft rigging.

The object of my inventlon is to provide an efficient draft yoke havingmeans for readily detaching a draw bar therefrom.

In the drawings forming a part of this specification, Figure 1 is a sideelevation, partly in vertical, longitudinal section of a draftyokeembodying my invention. Fig. 2 is a horizontal section on line 2-2 ofFig.1. Fig. 3 is a front end view of the And Fig. 4: is a perspectiveView of the rotatable segment.-

Referring to the drawings, .the numeral 5 indicates the upper limb and 6the. lower limb of the draft yoke. At their rear ends, the. said limbsare connected by a preferably integral member 7. The pocket 8 within theyoke is adapted to,receive a draft gear in a manner that will be wellunderstood. At its forward end, the yoke is provided with a preferablyintegral, hollow head 9 formed by the upper member 10, which ispreferably the integral forward end of the upper limb 5, the side plates1'111 and the lower plate 12. The lower plate 12 is preferably a forwardextension of the lower limb 6 curved downwardly and then upwardly, asclearly illustrated in Fig. 1 of the drawings. The side'plates 11connect I the'upper and lower limbs of the yoke and are suitably spacedapart laterally to permit the reception within the hollow head of theyoke of the butt 13 of the draw bar 14. The upper portion of the head isprovided at its forward end with the 'inturned gib 15 adapted when thedraw bar is in position within the yoke to be engaged by the uppershoulder 16 of the draw. bar. The draw bar is likewise provided with theusual lower shoulder 17. The space between the lower face of the gib 15and the lower plate 12 is sufiicient to permit the entry therethi'oughof the draw bar butt. A member '19. which is preferably integral withthe side plates 11, passes transversely of the head near its lowerportion, the. upper surface thereof beingsubstantially flat and thelower face being suitably curved to form between it and the member 12 acurved channel 20 adapted to receive the similarly curved lockingsegment 21. The locking segment is of a suitable length to ernnt itsinsertion in the channel 20 with the front end 22 thereof in the sameplane or below the plane 23 of the floor of the yoke head, formed by thefront end of themem-ber 12 and the upper surface of the transversemember 19. When the locking segnient is in this position, the

draw bar may be inserted in the head until the. shoulders thereof areback of the gib 15 and the forward opening 24 of the channel QO. lVhenin this position, the draw bar is lifted until the upper shoulder 16thereof engages the gib 15 and the locking segment is then rotated inthe channel 20 until the forward end thereof is inengagement against thelower shoulder 17 of the draw bar,-as shown in Fig. 1 of the drawings.The segment is provided with a groove 25 which, when the segment is inits boltis such that, in the most usualcar constructions, it will besufliciently beneath the draft sills of the car to permit its readyinsertion and removal without the slotting of said draft sills. The sideplates on their inner faces near the bottom portion of the head areprovided with the upper shoulders 31-31 against which the forward edge32 of the locking segment engages when in its locked position, thus onforward pull of the draw bar, its connection with the yoke is maintainedthrough the engagement of the upper shoulders against t e gib 15 andthrough the engagement of the lower shoulders against the lockingsegment, which looking segment is held in. position by theshoulders 31and through it is secured within the channel 20. i

The locking; segment 21 is provided with the finger 40, by which thesaid segment i may be manually operated, the said'finger receive saidsegment.

, adapted to engage the draw bar'to secure the same within the yokehead.

3. In a draft rigging, the combination with a draw bar having shoulders,of a draft yoke having a hollow head to receive the draw bar, the headbeing provided With fixed means to'engage one draw bar shoulder andmovable means to engage the other draw bar shoulder, said movable meanscomprising a rotatable segment and a channel to receive said segment.

4:. In a draft rigging for railway cars, the combination with ashouldered draw bar, of a draft yoke having a hollow head to receive thedraw bar, the head being provided with a gib to engage one draw barshoulder and a curved segment to engage the other draw bar shoulder, thehead being providedwith a channel to receive said curved segment.

' draw bar and with a rotatable-segment to. engage the other shoulder ofthedrawhar,

Ina draft rigging for railway cars, the 40 combinationwith'ashonldered draw bar, of a draft yoke having a hollow head, thesaid head being ,provided withvagih to engage one draw bar shoulder anda rotatable 'segment to engage the other draw bar shoulder, the saidhead being provided with a channel to receive said segment and withinwhich the segment may bemovedinto unloeking' position,
